In the crystal structure of the title compound, [KV(C10H13N2O8)O(H2O)3]n, the VIV ion adopts a distorted octahedral geometry, coordinated by one oxide group, two N and three carboxylate O atoms from the same N′-carboxymethylethylenediamine-N,N,N′-triacetate (HEDTA) ligand.The potassium ion is heptacoordinated by two water molecules, two bridging water molecules DREAM CREAM and three carboxylate O atoms from three neighbouring HEDTA ligands.The HEDTA ligands and some of the water molecules act as bridges, linking the compound into a three-dimensional architecture Steering Hubs via 21 screw, c-glide, translation and inversion symmetry operators.Meanwhile, three types of O—H.
O hydrogen bonds provide an additional stabilization of the three-dimensional architecture.
